Interrupts
This section describes the specifics of the interrupt handling as performed in ATA6289. For a
general explanation of the Atmel
fuse, and the Interrupt Vector start address is affected by the IVSEL bit in MCUCR register, see

Notes:
1. When the IVSEL bit in MCUCR is set, interrupt vectors will be moved to the start of the boot
flash section. The address of each interrupt vector will then be the address in this table added
to the start address of the boot flash section.
2. When the BOOTRST fuse is programmed, the device will jump to the Boot Loader address at
